I originally scanned this page of the December 1947 American Motorcycling Magazine for the Knucklehead in the Duckworth Chain advertisement. When I was getting ready to crop it I noticed the article above it "The List to End All Lists" which is a compilation of 112 American made motorcycles (as of 1947). One that I noticed that was missing is the Crouch.
